Robot coordinate system:      			World coordinate system:
      ^                 							^
      |x                							|y
   <--R                 							O-->
    y                     							x
angles from pi/2 to 3pi/2->0 to pi              angles from 0 to pi->0 to pi 
angles from pi/2 to -pi/2->0 to -pi				angles from pi to 2pi-> -pi to 0

	The idea is that for every command to the robot we use to world coodinate system
